VENTILATOR :son sirens.

To all whom z'zmay concern:

Bye it known that I, DANIEL I ay citizen of the-United States, -residln at Sayre, inthe county of Bradford and tateof Pennsylvania, have invented certain new and useful Improvements in. ventilatorsV for` Shoes, of which the following-is a specification.` y z J This invention relates to an improved shoe ventilator and has as one of its objects to provide a device of this character which may be readily applied at any approved point von the upper 0f a .shoe for Ventilating the shoe.

The invention'has as a further object to'y provide a ventilator which will be neat and unobtrusive in appearance so that the pres-` ence of the device upon a shoe will not mar the sightliness of the shoe. n.

The inventionhas as a still further object to provide a ventilator whichfwill be of eX- tremely simple construction and wherein, lifdesired, two or moreof .the ventilators may be employed upon a shoe and so arranged thatL movement of the foot within the shoe, incident to the operation of walking, will tend to set up a circulation of air through the shoe.

And the invention has as a still further object to provide a ventilator which may, if desired, be employed for' securing an ornament such as a bow, upon a shoe.

Other and incidental objects will appear hereinafter. lIn the drawings:

Figure 1 is a side elevation showing a conventional type of shoe equipped with a pair of my improved ventilators,

Fig. 2 is a sectional view taken on the line 2--2 of Fig. 1 and more particularly illustrating the construction and mounting of the device.

Fig. 3 is a perspective view showino the device in detail, the stud and cap empIoyed being separated,

Fig. 4 is a side elevation showing the use of my improxed device for securing a bow upon a slipper,`the slipper being conventionally illustrated,

Fig. 5 is a view particularly illustrating the plate employed for holding the bow, and

Fig. 6 is a sectional view showing the manner in which the ventilator clamps the bow upon the plate as well as secures the plate and bow upon a slipper.

In carrying the invention into effect, I employ a tubular stud 10 provided at its inner end with a head 11. Removably i Specification of Letters Ilatent.

threaded upon' the stud kat its outer end is a cap 12 and preferably,'theperiphery ofth-is vcap is mil-led'so thatthe cap may be easily rotated. lAs particularly shown in Fig-2, the cap is provided with an axial screw threaded socket to receive the outerV end-of `the stud and leading from this socket is a reduced axial` openinof 13 registering with the opening through t e stud. f

'In Fig. 1,I have shown a pair of my improved ventilators upon a conventional type of shoe 14. At least two ventilators are preferably employed and, as shownv in this figure, one ofthe ventilators may be vmounted `at the inner side .of the .toe of the shoe a short distance above the toe While the other may be arranged at'theinner side of the shoe mediallywith respect to the shank and preferably just above the shank. In mountingthe ventilator, an opening of proper size isfirst punched through they leather of the shoe, whenthefstud 11 is then inserted;

through this opening from the inner side of the shoe., The `cap 12 is then applied to the outer end of the stud and adjusted to tightly bind the ventilator in position. In this connection it should be observed that when forming the ventilator receiving openings in the shoe care should be taken that such openings will each be of a size to snugly receive the ventilator stud therethrough and preferably, a special punch will be provided for forming these openings. As will be noted, a pair of the ventilators when applied to a shoe, as shown in' Fig. 1, will not detract from t-he appearance of the shoe. Movement of the foot within the shoe, incident to the operation of walking will, of course, tend to draw air in through one of the ventilators and expel the air from the other of the ventilators. Consequently, a circulation of air within the shoe will be had for eifectuallyvventilating the shoe.

In Figs. 4, 5 and 6 of the drawings, I have illustrated a slight modification of the invention showing the use of Inv improved ventilator as an ornament securing device. A plate 15 is employed. This plate may be formed from a piece of suitable resilient sheet metal and is provided adjacent opposite ends thereof with openings 16. Lapped back and forth across the front face of the plate is a piece of ribbon forming a bow 17 The ends of the ribbony are inserted through the openings 16 in the plate when the overlapping portions of the bow are all stitched together at their edges medially of the bow. In this way, a bow may be readily formed from a piece of ribbon while, at the same time, the bow will be fastened to the plate l5. Furthermore, it wil be robserved that the plate will be obscured by the bow.

a `conventional slipper 18. This is accomplished by rst inserting the ventilator stud through the upper end portion of the slippervamp, yas ishown in detail in Fig.r6.

i' The plate l5 is then fitted over the stud,

this plate being formedcentrallywith a suitable opening to freely .receive the stud while thel bow 17 is also formed with an opening to register with the opening of the plate. The ventilator cap is then threaded down upon the stud forconnecting the ventilator withthe shoe'and clamping the plate upon the stud. Thus, the ventilator will support the bow in the usual position upon the slipper while, at the same time, the ventilator will act to admit air within the slipper. Furthermore, it will be seen that the ventilator cap willl bind against the material f of the bow so as to prevent possible lateral shifting of the` bow upon its supporting plate and will also form, in effect, an ornamental button centrally of the bow so as to produce a very pleasing appearance. Also, it is to be particularly observed that owing to the soft and pliable nature of the material of the bow, the bow fabric will coact with the ventilator cap to prevent retrograde movement thereof upon the stud of the ventilator and will tend to lock the cap in position upon the stud binding the ventilator upon the shoe and securely holding the plate 15 to su port thebow rextending transversely of the s ipper. Having thus described the invention, what is claimedl as new is: n .The combination with a shoe,'of a plate bearing against the outer surface Vof the shoev near the toe portion thereof and provided with spaced transverse slots. and an intermediate opening, a ribbony threaded through the slots `and over the opening to form a bow,-an exteriorly threaded stud extending through theopening in the platey and piercing the ribbon, said stud being provided throughout its length with an Aaperturecommunicating with the interior of the shoel and having an enlarged head bearing against the inner surface of said shoe, and an internally threaded ycap engagingv the eX- terior threads of the stud and providedwith an aperture registering with the'apertureV in the stud, said cap bearing against the ribbon and serving to clamp the bow, plate and stud in position onthe shoe.

In testimony whereof I aix my signature. 'Y
